Aptana not recognizing coffee as a file type

Aptana doesnt seem to want to recognize *.coffee (coffeescript files) as a file it knows about despite the following:

• Coffeescript is installed on the machine using npm


• A bundle exists within the commands tab for coffeescript


• The entire aptana suite has been uninstalled and reinstalled a couple of times


• *.coffee does not appear in known file associations of Aptana

What are the steps to get Aptana to recognize coffeescript as something that needs syntax highlighting and can be compiled down to javascript as expected? (aka setting up the editor again)

One computer I have has everything working fine in terms of the above, another seems to refuse working in the same manner. Is there some settings file that I can copy across that would force the same behavior for both?
